Subject: [PATCH 3/7] drm/i915: Mask out the HPD irq bits before setting them individually.
Date: Tue, 16 Apr 2013 13:36:56 +0200 [thread overview]
Message-ID: <1366112220-7638-3-git-send-email-eich@suse.de> (raw)
In-Reply-To: <1366112220-7638-1-git-send-email-eich@suse.de>
To disable previously enabled HPD IRQs we need to reset them and
set the enabled ones individually.
